1 Alcohol consumption WHO methodology Dr Alexandra Fleischmann, Mr Dag Rekve and Dr Vladimir Poznyak Management of Substance Abuse Unit (MSB) Department of Mental Health and Substance Abuse, WHO, Geneva October

2 Who is WHO? UN specialized agency for health (1948) The directing and co-ordinating authority on international health work 194 countries (Ministries of Health) Headquarters in Geneva, 6 regional offices, 151 country offices

3 WHO s Role in population health statistics WHO is constitutionally mandated to: "establish and maintain.. epidemiological and statistical services" "assist in developing an informed public opinion among all peoples on matters of health" WHO reform process defined 5 core functions, including: collection, analysis and dissemination of evidence on health trends and determinants setting targets, monitoring progress, measuring impact in terms of lives saved, risks averted and coverage of essential services UN and World Health Assembly Resolutions provide mandates for: monitoring of health targets, e.g. SDG and NCD targets regular reporting on key indicators e.g. tobacco, alcohol

5 Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER) Reporting guidelines for new estimates of health status and some health determinants (including substance use) published in Lancet and PLOS Medicine in June, 2016 Developed by a working group convened by WHO, including IHME and other partners, with extensive outreach and comment periods Aim is to provide sufficient information for users to understand limitations & potentially reproduce analyses Some reporting items will be challenging for producers of estimates: existing datasets may not be documented in alignment with GATHER open-access of input data, and access to computer code are both required; these imply additional reporting burden when publishing estimates quantification of uncertainty is required: this is an active area of research

6 WHO Policy on official health statistics Ideally based on standardized analysis of primary datasets with adjustments for all known biases: clearance criteria met, including GATHER compliance and country consultation consultation does not require WHO and country reach consensus WHO estimates only revised based on received information that meets inclusion criteria compliance with transparency and reporting criteria WHO statistics may be published with a disclaimer that they may differ from official national statistics (which may be derived using alternate valid methods and assumptions)

7 Clearance of new health statistics Official WHO health statistics are cleared by Information, Evidence and Research. Financial and cost-effectiveness statistics are cleared by Health Governance and Financing. We evaluate: high-quality database of evidence methods are appropriate statistics are consistent with other health estimates compliance with transparency and reporting criteria expert review of methods and results country consultation if country-level estimates involved

8 Global strategy to reduce the harmful use of alcohol The vision behind the global strategy is improved health and social outcomes for individuals, families and communities, with considerably reduced morbidity and mortality due to harmful use of alcohol and their ensuing social consequences. Harmful use of alcohol is broad and encompasses the drinking that causes detrimental health and social consequences for: the drinker the people around the drinker society at large as well as the patterns of drinking that are associated with increased risk of adverse health outcomes.

9 What actions are needed to reduce the harmful use of alcohol? Global, regional and national actions on: levels of alcohol consumption patterns of alcohol consumption contexts of alcohol consumption wider social determinants of health Special attention needs to be given to reducing harm to people other than the drinker and to populations that are at particular risk from harmful use of alcohol.

10 WHO Global NCD Action Plan Key risk factors Tobacco use Harmful use of alcohol Unhealthy diet Physical inactivity Key cost-effective interventions (updated appendix 3, WHA70.11 ) Harmful use of alcohol Increase excise taxes on alcoholic beverages Enact and enforce bans or comprehensive restrictions on exposure to alcohol advertising (across multiple types of media) Enact and enforce restrictions on the physical availability of retailed alcohol (via reduced hours of sale) Enact and enforce drink-driving laws and blood alcohol concentration limits via sobriety checkpoints Provide brief psychosocial intervention for persons with hazardous and harmful alcohol use

11 NCD global monitoring framework: alcohol-related targets and indicators One target: At least 10% relative reduction in the harmful use of alcohol, as appropriate, within the national context by 2025 Indicators: total (recorded and unrecorded) alcohol per capita (15+ years old) consumption age-standardized prevalence of heavy episodic drinking alcohol-related morbidity and mortality

12

13 3.5 Strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol Coverage of treatment interventions (pharmacological, psychosocial and rehabilitation and aftercare services) for substance use disorders Harmful use of alcohol, defined according to the national context as alcohol per capita consumption (aged 15 years and older) within a calendar year in litres of pure alcohol

14 SDG data flows Source: UNSD

15 Total per capita (15+) alcohol consumption globally in 2016 Reported by WHO to the UNSD as part of the SDG reporting Source: WHO World Health Statistics 2017

16 Conceptual causal model of alcohol consumption and health outcomes Societal Vulnerability factors Level of development Culture Drinking context Alcohol consumption Volume Pattern Health outcomes Chronic Acute Individual Vulnerability factors Age Gender Family factors Alcohol production, distribution, regulation Mortality by cause Socio-economic consequences Harm to others Socioeconomic status WHO Global Status Report on Alcohol and Health 2014

32 Looking to the future WHO aim to synthesize data to obtain comparable health estimates using standard methods, assumptions and bias adjustments data are often not comparable across time, populations and data collection mechanisms (requires adjustment) data are often sparse (use modeling) increasing demand from countries and international organizations for frequent, timely and accurate estimates SDG era will result in a substantially expanded list of indicators requiring consultation and likely place greater demands on countries political pressure can become extreme. if WHO moves to increased use of externally generated statistics (eg. IHME), how does WHO continue to address these issues?
